A battery less sensor node that can be used in star configuration to create mesh networks of sensors… http://www.enocean.com/indexenc6.html Main application seems to have been wireless light switches to date.
Staying in Hotel Skt Petri tonight. Nice website but just wanted to find a picture of the place… also led me to find http://www.designhotels.com/ which looks handy for trying to find nice hotels for those city stop overs…
Set-up another 19 node network of Micaz motes with 6 mts310 sensor boards and 13 mts300 sensor boards. Running mts310CB code in low power mode. I initially sat all the motes together (image above) to see how close the various sensor readings were, a crude callibration test. The graph below
Just registered for UbiComp2006. Hoping to take the time out to pull together some writing on Ubiquitous Computing for Arup as part of our Drivers of Change. Also will be visiting the LA office to speak about wireless sensor networks and the DTI work.
Just registered for this IMI event at RIBA in October. Speakers include Usman Haque.
Would be nice to use this processing library to represent temperature in an environment – *how fast the fire is burning*.
Have had a frustrating day with this accelerometer – cannot figure out the code calculating the actual acceleration in Arduino – see forum posting.
A great example of how people are using Arduino as an input conduit to design product…. uses a home made pressure sensor (conductive wire grids separated by foam) around a punch bag as the input device, the ouptut is a 3D model of the object to be made. Great video,
Just back from 2 days with Artificialtourism getting some hands on experience with Arduino. After a morning of intros to Arduino, basic does and don’ts and looking at sensors available we got onto building some prototypes. First up was using a tri colour LED (see Farnell) with a simple cross
“Perpetuum’s vibration energy-harvesting microgenerator is an enabling technology that makes wireless, battery-free sensors a reality.” Forwarded by a colleague at Arup – Paul Fuller – good to see that a UK product is pitching for the holy grail of energy harvester for wireless sensor networks.
Came across this nice image of toughened glass viewed through polarised glasses on wikipedia under their polarisation entry. I had been looking up info on Anisotropy for an image analysis project I am doing at Arup. Have been implementing some basic algorithms in processing using co-occurance matrices and simple thresholding
